Interface Configuration Dialog Box
v Note: If you need more information about bridging, see “Bridging 101”
in the Appendices to this manual.
To access this dialog box, select Interface/Bridging from the Device View.
This can be done for any type of interface except IP subinterfaces.
Bridging operates on physical network addresses (such as Ethernet
addresses), rather than logical addresses (such as IP or IPX addresses). From
the standpoint of routing, router interfaces which are set to bridge between
themselves appear as a single logical entity.
Thus, a “Bridge Group” is made up of all of the physical network interfaces
in a router which have been set to bridge the same protocol. Whether an inter-
face bridges a protocol is set in the protocol configuration dialog box for each
individual physical interface. See, for instance, the IP Routing/Bridging/Off
radio buttons in the TCP/IP Routing: Ethernet Configuration Dialog Box.
Each Bridge Group can have routing parameters set for it. All of the interfaces
in the group share these parameters. To access the dialog boxes which set
these parameters, select Protocol/Bridging for the desired protocol (e.g. IP,
IPX, etc.).
